A graft is prepared for attachment to an acromion. Two sutures are attached to corners of the graft. The two sutures are loaded into an introducer instrument, and the introducer instrument spreads the graft open. The graft is then positioned under the acromion. Strands of like sutures are tied on a medial side of the acromion to attach the graft to the acromion. The sutures are trimmed after knotting, securing the graft to the acromion.
